POLE-TO]? LAMP-FIXTURE.

Specification of Letters Patent.

Application filed July, 7, 1914. Serial No. 849,381.

To all whom it may concern Be it known that I, ALBERT H. WINTER Jornnu, a subject of the King of Great Britain, and resident of the city of Toronto, county of York, Province of Ontario, in the Dominion of Canada, have invented certain new and useful Improvements in Pole-Top Lamp-Fixtures, described in the following specification and illustrated in the accompanying drawings, that form part of the same.

The principal objects of the invention are, to facilitate the placing and removal of the lamps and globes and to obviate the breaking or damaging of the globe cap and lamp in the event of the breaking of the globe.

A further object is to devise a form of fixture in which the cap is rigidly supported in such a manner that the cleaning of the globe would not be interfered with.

The principal feature of the invention consists in the novel construction and arrangement of parts, whereby the lamp and the electrical connections thereto are rendered readily separable from the base and electrical feed connections, and whereby the lamp and globe cap are rigidly supported rom the base.

In the drawings, Figure 1 is an elevational and part vertical sectional view of a lamp fixture constructed in accordance with this invention. Fig. 2 is a perspective detail of the interior support for the globe cap showing the electrical block connector, and Fig. 3 is a sectional detail through one of the globe ring supporting lugs. Fig. 4 is an enlarged vertical sectional detail of the lower end of the lamp supporting member and of the separable electrical connections.

Like numerals of reference indicate corresponding parts in each figure.

Referring to the drawings, 1 is the base ring adapted to rest upon the pole top flange 2 having an outwardly projecting weathering flange at the bottom and downwardly extending lugs 3 to engage the inner side of the flange 2, the ring being held in place by the bolts i. The upper side of the ring 1 is formed with a channel groove 6 adapted to receive the bottom rim 5 of the globe 7.

8 is a V-shaped bracket secured to the inner side of the ring 1 and extending centrally thereacross and supporting a suitable form of electrical screw socket 9. centrally arranged.

10 is a spider ring having the outwardly projecting arms 11 adapted to rest upon the inner flange 12 of the base ring 1.

13 are lugs projecting inwardly from the ring 10 and supporting an electrical plug connector 14 which is adapted to screw into the socket 9. The plug is provided with a central stem 15 adapted to engage one electrical terminal in the socket and the outer shell 16 forms the contact with the other terminal.

17 is a socket formed inthe spider 10 preferably arranged at an outward incline in which the lower end of the supporting tube 18 is secured, said tube being held rigidly in place by the pin 19. The tube 18 is preferably flattened above the ring and is bent into perpendicular position having the upper extremity round and upon this upper extremity is secured a spider 20.

21 is the globe cap here shown of spun metal, formed in two sections, though it must be understood that any desirable form may be used, said cap'being secured to the arms of the spider 20, the globe cap is thus rigidly supported from the base.

22 is a lamp socket suitably secured in the top of the globe cap and carrying the inverted lamp 23.

From this description it will be seen that the globe cap is rigidly supported from the ring 1 and the plug 14: is rigidly secured to said ring. The electric wires 2% connect to the lamp socket at the top leadingdownwardly through the tubular support 18 and immerging from the bottom are connected to the terminals of the plug consequently when it is desired to remove the lamp or to obtain access to the interior of the globe it is merely necessary to rotate the globe cap and through the tube support 18 the plug 14 will be unscrewed from the socket 9, thereby disconnecting the lamp and also removing the cap and inner frame work and allowing the globe to be lifted off and readily cleaned. The electrical plug and socket connections for theremovable lamp supporting member are herein shown and described as being of the screw variety but any desirable form of separable electrical connectors may be used. It will also be seen that in the event of the globe being broken the supporting tube 18 Will carry the globe top and lamp without injury. The support 18 is flattenedintermediate of its length in order to reduce the shadow on the globe to the smallest possible extent.

The ring 1 is provided with suitable ducts 25 extending angular-1y downward and out ward from the groove 5 so that rain falling upon the globe will be drained to the exterior of the fixture.

26 is a reflector oi cone shape supported upon the ring 10 below the lamp and adapted to direct the rays of light outwardly to the globe.

What I claim as my invention is 1. A pole top lamp fixture, comprising, a globe supporting base, an electrical connection arranged upon said base, a removable member extending upwardly from said base and having an electrical connection at its lower end engaging the electrical connection in said base, and a lamp supported upon said removable member and electrically connected with the electrical connection carried thereby.
